Propelling The World Since 1984

GSC Systems is one of the oldest and most globally-renowned propeller manufacturing companies for the light aircraft and airboat industries today.

We began with handmade hardwood fixed-pitch propellers and also developed the ground adjustable TECH II and TECH III. With the TECH series, customers are able to replace single blades rather than changing the complete propeller.

Tech Series Propellers

Construction of fixed-pitch propellers are such that the wood fibres in the laminations run the entire length of the propeller, allowing it to absorb considerable harmonic vibrations from the engine or crankshaft.

Because of this superior strength, GSC Systems will suggest that a fixed pitch propeller be used on any direct-drive engine (such as Subaru®, Jabiru® and Volkswagen®. Generally a fixed-pitch propeller is a less-expensive option than an adjustable propeller. Additionally, they are ideal for flyers that wish to be able to attach their propellers and immediately be ready to fly, with no further effort required for adjusting. The fixed-pitch propellers can be ordered in hub thicknesses between 1 ½” up to 2 3/8”. Diameters are available from 32” up to 72”. Specialty fixed-pitch propellers can be made on request.

PPG | Powered Paraglider Propellers

GSC Systems have been in the light aircraft propeller market for over 30 years, and have also provided quality products to the small trike and PPG propeller market. With our modern production equipment, we can offer the PPG customer the same high-quality products that our conventional aircraft customers have depended upon.

Our PPG propeller database covers the majority of the props that are currently in use. However with new OEM's and new engines coming to market, many prop manufacturers aren’t able to keep up. Our advantage is that we have a CMM in house, which means if you have a unique or damaged prop, we can duplicate the original. Even better, we can even modify it if necessary to get the optimum RPM and thrust that you require. At GSC Systems we offer you the best of both worlds; a complete line of fixed-pitch props, or choose from our 2-blade and 3-blade fully ground-adjustable product lines. Our very light CNC machined aluminum hub enables you to break down the propeller to accommodate a very small shipping size, when you take your PPG on holidays with you. In the event of a prop strike, you may need to change only one blade and with our multi-blade hub system, you can easily carry spares for quick changes.
